NEET BIOLOGY

Detailed explanation-1: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.

Detailed explanation-2: -Sexual reproduction allows for a greater genetic diversity through the process of Fertilisation. It involves the meiosis process which means a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.

Detailed explanation-3: -About 1.3 billion years ago, sexual reproduction starts mixing genes and paves the way for the great diversity we see today. It’s hugely important on this timeline because it allows organisms to begin combing genes, allowing the next generation to do more than its parents; upping the chance of survival.

Detailed explanation-4: -The advantages of sexual reproduction: produces genetic variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage. a disease is less likely to affect all the individuals in a population.

Detailed explanation-5: -Sexual reproduction, which involved the formation of gametes through meiosis and the fertilization of the gametes where two gametes fuse to make one diploid cell, offers the greatest potential for genetic diversity.
